Deep Rectus Sheath (DRS) Block in Abdominal Surgery

The goal of this observational study is to learn about the effectiveness of the Deep Rectus Sheath (Preperitoneal) block in patients undergoing abdominal surgery. The main question it aims to answer is: Does the Deep Rectus Sheath block improve postoperative recovery and pain control compared to standard care or other fascial plane blocks in patients undergoing abdominal surgery? Participants undergoing open or laparoscopic abdominal surgery as part of their routine clinical care will receive analgesic management according to standard practice, which may include systemic analgesia alone, Deep Rectus Sheath block, or other fascial plane blocks (such as TAP, ESP, or QL), depending on anesthesiologist choice. Postoperative outcomes will be collected prospectively, including quality of recovery (QoR-15 at 24 hours), pain scores at rest and during movement up to 48 hours, analgesic consumption, time to first analgesic request, mobilization time, and occurrence of complications.
